Outlook outages were caused due to DDoS attacks confirms Microsoft

The attacker known by Microsoft as Storm-1359, also known as Anonymous Sudan, is blamed for the cyberattacks.

Layer 7 DDoS assaults against Microsoft's services caused recent disruptions to the Azure, Outlook, and OneDrive web portals, according to Microsoft. The attacker known by Microsoft as Storm-1359, also known as Anonymous Sudan, is blamed for the cyberattacks. The disruptions started at the start of June, with OneDrive targeted on June 8 and the Microsoft Azure Portal on June 9; Outlook.com's web portal was targeted on June 7. Microsoft did not disclose at the moment that their servers were being subjected to attacks using DDoS, but they made a suggestion that they were the reason for them when they said, for some incidents, that they were "applying load balancing processes in order to mitigate the issue."

Microsoft also suggested DDoS assaults in a preliminary root cause analysis made public last week, which claimed that an increase in network traffic was to blame for the Azure outage. Microsoft has stated that the company noticed a sudden spike in its network traffic, which affected the company’s ability to manage the traffic coming into these sites and thus prevented users from accessing them. However, Anonymous Sudan has shown that they've got enormous resources at their disposal, and so financial institutions must remain on guard for possible outages even though there has been no indication that attacks on European banking systems have begun.
